Troubleshooting

When you troubleshoot issues with a network adapter, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

Ethernet cables

Network devices

Computer system

To test your setup components, try the following:

Use the Ethernet cables, network devices, and computer system in another setup to see if the problem is with the components or the setup.

Use different Ethernet cables, network devices, and a different computer system in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test your cables, it is recommended that you do the following:

Test each cable individually.

Use short cables when you are testing.

When you test the Ethernet cables, network devices, and computer system, it is recommended that you do the following:

If the device is listed with an error, follow the instructions on the product page to reinstall the drivers.

Check to see if your network devices (for example, a network switch, router, and so on) use compatible protocols (for example, 10/100, Gigabit, and so on).

Make sure that the link LEDs on the adapter are illuminated when it is plugged into a network device. If the link LEDs are illuminated, it means that a good electrical connection exists between the devices.

If you use a wall jack with an Ethernet cable, make sure that the jack is patched in properly.

If you are experiencing speed or connectivity issues, it is best to set a specific speed at half or full duplex in your settings. You can set your network adapter to perform at a certain speed, but the device that the adapter is connected to (whether it is a router, switch, or computer) must also be able to perform at the same speed.

Note: You must log in as the local administrator before you continue.

To open Device Manager:

Press Windows key + R.

Type devmgmt.msc.

Click OK.

Open the Networking adapters section.

Right-click the network adapter that you want to change and select Properties.

Click the Advanced tab.

Scroll down to Speed & Duplex. By default, it is set to Auto-Negotiate. Select any of the speeds that you see in the list.
